Epidermal growth factor (EGF) rapidly stimulates the formation of inositol 1,4,5-trisphosphate in a variety of cell types. Previously we have found that in intact cells stimulation of phospholipase C (PLC) activity by EGF is correlated with the retention of increased amounts of PLC activity by a phosphotyrosine immunoaffinity matrix, suggesting that the EGF-receptor tyrosine kinase phosphorylat...

Crosslinking of the low affinity immunoglobulin G (IgG) Fc receptor (Fc gamma R type III) on natural killer (NK) cells initiates antibody-dependent cellular cytotoxicity. During this process, Fc gamma R stimulation results in the rapid activation of phospholipase C (PLC), which hydrolyzes membrane phosphoinositides, generating inositol-1,4,5-trisphosphate and sn-1,2-diacylglycerol as second mes...

We have recently shown that synthetic peptides of the effector domain of the low-molecular-mass GTP-binding protein Rab3 stimulate inositol 1,4,5-trisphosphate production in various permeabilized cells. To investigate the mechanism of the peptide-induced activation of phospholipase C (PLC) and to identify the PLC isoenzyme(s) targeted by these peptides, isolated pancreatic acinar membranes and ...

Moby/plc is a graphical design tool for PLC-Automata, a special class of hierarchical real-time automata suitable for the description of distributed real-time systems that are implementable on a widely used hardware platform, so-called Programmable Logic Controllers (PLCs). In this paper we sketch the modelling language in use and some features of Moby/plc, like several validation methods and c...

Staphylococcus aureus secretes a phosphatidylinositol (PI)-specific phospholipase C (PI-PLC) which is able to hydrolyze the membrane lipid PI and membrane protein anchors containing glycosyl-PI. The gene for PI-PLC (plc) was cloned from S. aureus into Escherichia coli. Oligonucleotide probes based on partial protein sequence and polyclonal antibodies raised against the purified protein were use...

Phospholipase C (PLC) regulates a number of cellular behaviours including cell motility, cell transformation, differentiation and cell growth. PLC plays a regulatory role in cancer cells partly by acting as signalling intermediates for cytokines such as EGF and interleukins. The current study examined the expression of the PLC isozymes in human breast cancer and corresponding clinical relevance...

Background: Thoracolumbar spinal fractures include a range of injuries of various severities from simple apophysealfractures to neurological injury and complex fractures associated with vertebral dislocation. The treatment ofthoracolumbar fractures is challenging, especially due to the difficulty of evaluating the posterior ligamentous complex(PLC). The purpose of this study w...

Presented in the paper is the PLC symbol naming rules in order to simulate the virtual factory which is operated by the PLC control logic. In the PLC simulation, the corresponding model, normally called as the plant model, to the PLC receives the PLC output signal, operates virtual devices, and sends the changed PLC input signal which is updated by the virtual device movements. Therefore the pl...

The importance of PLC activation in cell proliferation is evident from the fact that the hydrolysis of PtdIns(4,5)P2 is one of the early events that follow the interaction of many growth factors and mitogens with their respective receptors. However, the importance of PLC activation is not restricted to proliferation; it is one of the most common transmembrane signaling events elicited by recept...
